Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description mentions that supplied proofs are verified and provider effects remain external, which gives some transparency about side effects. However, it does not clarify whether 'advance' is a mutating operation or if there are any destructive actions. It also doesn't address authentication or error behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is succinct with two sentences, front-loading the core purpose. It avoids unnecessary detail, making it easy to scan.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has seven parameters and no schema descriptions, the description is too minimal to fully convey the tool's semantics. It mentions a 'scoped lifecycle' and 'proofs' but does not explain these concepts or how they relate to the parameters. Additional context is needed for effective usage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has no descriptions for the seven parameters, and the tool description provides no information about what each parameter means. This leaves the agent without guidance on how to populate them, especially the required project_id and bundle_json.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool inspects or advances subscriptions within a scoped lifecycle, providing a verb-resource pair. It also mentions proof verification and external provider effects, adding context. However, the term 'advance' is ambiguous but still understandable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description does not explicitly mention when to use this tool versus alternatives. It provides no conditions or contrast with sibling tools, so an agent would have to infer usage.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
